Super Clicky Fidget Button – Nút bấm click 2 trạng thái

This is a 2-state click button with an internal mechanism similar to that of a retractable pen. 

This can be used with or without a long M3 bolt to transfer the click action into a secondary linear or rotary motion. Use the case with holes to see the cam pop in and out of view each click.

Hardware

Required

A spring that is about 15mm long and 5mm in diameter. The design can use larger and smaller springs, but this size worked best for me.

Spring harvested from a standard click pen are a little longer than needed, but should work. If the click mechanism feels too stiff, shorten the spring with wire cutters.

I had a little success creating a spring out of PLA filament softened in hot water. This would probably work if you're willing to test different coil sizes, but metal springs will still be best.

Optional

A long M3 bolt to transfer the click action out of the device for some secondary purpose - or just to demonstrate the change in distance caused by the click.

Printing

All parts can be printed without supports.

The cam includes a thin 1 layer bridge over the bolt hole. If you intend to use a bolt, puncture that bridge with the bolt.

Getting a good click

I found the the button click improves after using it for a while.

Some people have added wax or Vaseline to the sliding parts.

If the button is still sticking, try printing the cap and button at a 0.16mm layer height, and the cam at 0.2mm. This guarantees that the sliding surfaces have slightly offset "steps" and are less likely to catch.
